It's important to mention the fact that the C6 Corvette gauge cluster can only be used if you are using a BCM (body control module). I didn't purchase the ISIS wiring harness. My wiring is basically taken from a C6 Vette. All the "not used" features are depinned from the harness. I built the engine harness the same way.
Since you are using the BCM are you going to control the alternator with it, this will reduce drag by the alternator when the battery is fully charged and over charging? Depending on the system you may need to get other parts from GM to make that work. The alternator control has been on most cars since the 90's for better mileage.
If someone were to put the battery in the cabin this would also help.
If you are interested in Alternator control this is MegaSquirt's forum site. For those wondering MegaSquirt 3 is an engine control for EFI mostly for racers and DIY that do not need meet the rules for the street. It does go into a lot of detail.
I didn't want any galvanic corrosion interfering with the connections.
You also should use Noalox Anti-Oxidant Compound for reducing galvanic corrosion on any mechanical connections running electricity though it. It can be purchased at Home Depot or electrical supply house.
Look's great and see why it wins awards!!
